Compounded Amoxicillin for Pets
Cats refuse amoxicillin tablets and the commercial liquid is mildly bitter. Compounded fish-flavored suspensions are widely available for cats. Birds need much higher per-kg dosing than commercial preparations — compounded avian-strength liquid is the standard.
Why Chewy Pharmacy can't fulfil this prescription
Chewy stocks commercial human amoxicillin tablets and capsules. No avian-strength liquid; no flavored feline suspension.

Species-specific benefit
Skin, urinary, and respiratory infections in cats require 10–14 day daily dosing. Compounded fish-flavored liquid dramatically improves owner compliance vs commercial tablets.
Avian metabolism requires 150–175 mg/kg dosing — about 10x higher per kg than mammals. Commercial amoxicillin can’t deliver these concentrations practically. Compounded avian-strength liquid is the standard form.
